DESCRIPTION
The DS100BR111A is an extremely low power, high
performance dual-channel repeater for serial links
with data rates up to 10.3 Gbps. The DS100BR210A
features one bidirectional lane (one transmit, one
receive channel).
The DS100BR111A features a powerful continuous
time linear equalizer (CTLE) to provide a boost of up
to +36 dB at 5 GHz and open an input eye that is
completely closed due to inter-symbol interference
(ISI) induced by the interconnect mediums such as
an FR-4 backplane or AWG-30 cables. The
transmitter features a programmable output de-
emphasis driver with up to -12 dB and allows
amplitude voltage levels to be selected from 600
mVp-p to 1200 mVp-p to suit multiple application
scenarios.
The programmable settings can be applied via pin
settings, SMBus (I2C) protocol or an external
EEPROM. When operating in the EEPROM mode,
the configuration information is automatically loaded
on power up – This eliminates the need for an
external microprocessor or software driver.
Part of the PowerWise family of energy efficient
devices, the DS100BR111A consumes just 65
mW/channel (typical), and allow the option to turn-off
unused channels. This ultra low power consumption
eliminates the need for external heat sinks and
simplifies thermal management in active cable
applications.
